4 Claims.

The present invention relates to tank valves and more particularly to a novel supply and ilushing mechanism for a toilet, water-closet or the like, or wherever a ilushing operation is desired. L

Among the objects of the present invention is the provision of a novel supply valve and mecha` nism for operating the same whereby to more quickly and eiciently rell a supply tank after the flushingoperation.

A further object of the invention is the provision of a novel float construction operable in an auxiliary receptacle or tank for opening and closing the supply valve.

Another object of the present invention is the provision of a novel mufiler construction for the supply outlet whereby to silence the rush of water therethrough' and into the tank.

A still further object is the .provision of a novel construction of casting or base which not only forms a mounting for the secondary or auxiliary tank but also provides a concave seat for the ball valve. I

Another object is the provision of novel adjusting means and mechanism-for the stems of the ball and oatvalves whereby such stems may be mounted and maintained in perfect adjustment tion, combination and arrangement of parts illustrated in the accompanyingI drawing, and While I have shown therein a preferred embodiment, it is to be understood that the same is susceptible of modification and change, and comprehends other details, arrangements of parts, features and constructions without departing from the spirit of the invention. A

In the drawing:

Fig. 1 is a view in vertical cross-section through a ilush or supply tank and showing the novel invention, part in side elevation and part in vertical cross-section.

Fig. 2 is a top plan view of the novel invention.

Fig. 3 is an enlarged view in horizontal crosssection through the ballcock or valve.

' Fig. 4 is a view in vertical cross-section through the novel adjustable rocker arm.

Referring more particularly to the disclosure in the drawing, the numerals I and 2 refer to the base and a side or end wall of a supply tank for a toilet, water-closet or the like. In the base of this tank is suitably mounted a supply or intake pipe 3 having a coupling 4 leading from and connected to a usual water supply system, and a discharge pipe 5 of considerably greater crosssection or diameter leading to the bowl of the toilet or the like (not shown).

The supply or intake pipe 3 is connected to an elbow 6 by means of a union 'I, the other end of the elbow being connected to a novel ballcock or valve 8. This ballcock or valve construction comprises a removable housing or casing 9 in which is positioned a renewable valve seat II] seating at its lower end against a shoulder Il 'in the casing and maintainedv in position by means of a hollow body or sleeve I2 provided with a series of discharge openings I3 around its periphery. This sleeve is locked in position by means of a packing box nut III threaded on the one end of the housing .or casing and, enclosing suitable packing material for sealing the valve against leakage.

The sleeve I2 is interiorly threaded to receive the threads `I 5 of the rotatable Valve member I6. This member at its inner end is provided with an enlarged hollow head I1 for the reception of a renewable washer or seat I8at formed of composition or the like. The stem I8A of the valve member I6 is operated by means of an arm I9 having Vits one end 20 mounted o`n the stem and its opposite end 2I carrying a float 22. This oat is connected to the arm AIcy means of a stem 23 threaded in an adjustable rocker arm 24Ywhich `is pivotally mounted upon a bolt or the like 25, the end of the bolt being threaded in a member 26 having a semi-circular opening for receiving Cil the reduced end 2| of the arm I9. -By means of this construction, the float and its stem may always be maintained in perfect .alignment and the rocker adjusted upon the arm I9. l

The iloat 22 is movable in a secondary or auxiliary tank 21 open at-its upper end and its lower end threaded in a base 281 In its preferred ernbe retained on the overflow by means of bolt' 39 and nut 40. The guide arm is provided withl an adjusting not 4| in which isla boit 42, A wing trip lever and whereby the ball valve 33 may `be raised from its seat to permit a flushing of the toilet.

In the operation of the novel invention, and assuming that the main iiush or supply tank is filled to the desired height, a tripping of the tank lever will raise the ball valve 33 to permit a discharge of the'accumulated water from the main tank as well as from the auxiliary tank 21 i through its outlet 34 into'the main dischargey When thevwater has been completely pipe 5. v discharged, the ball valve will reseat and the float 22 will drop because of its weight and thereby lower the end 2I` of the arm I9, whereby to turn the valve stem I8 and separate the valve parts in the ballcock or valve 3 to permit Water to flow from the supply pipe, through the valve and then through the inlet pipe 48. In order to silence the water passing throughv the Ainlet the invention comprehends the provision of a muiller 43. This muiller or silencing means comprises a cup or receptacle 50 positioned below and spaced from the discharge end of the inlet pipe, and a skirt 5I concentrically spaced from said cup by means of a plurality of spacers 52. 'I'hus the water nowing from said inlet pipe 43 must discharge into the cup 50, and from there over the sides thereof and downwardly between the cup and overhanging skirt 5l.

Also leading from the inlet pipe 48 is a relatively small inlet 53 leading to and permitting the passage of a small amount of water to the overilow 3l. This water provides an afterilll for sealing the trap of the bowl.

When the ballcock or valve 8 Iis opened, the water discharging into the main tank quickly increases in depth until it overows in the auxiliary or secondary tank 21. The accumulated water in the auxiliary tank will raise the float 22, causing the arm I9 to be raised and thereby turn the valve stem I8 to close the ballcock or valve 8.

It will be readily seen from the above description and the disclosure,4 that the ballcock or valve will be completely open until the tank has been completely lled since the water which trips the valveis overflow from the tank. This permits a lling of the tank in considerably less time than with prior constructions, as Well as a minimum wear upon the valve parts which are 2,088,864 Y L'quickly and fully opened and closed when the ballcock or valve is operated.

By means of the muliler arrangement, the discharged water is silenced. Also the valve construction is much more positive in operation, and by making the discharge pipe from the tank as a casting which also forms the ball seat as well as the base for the overflow and auxiliary tank, a less expensive and more readily assembled construction is. produced.v

Having thus disclosed the invention, I claim:

1. In a ush tank construction, an auxiliary tank therefor provided with means for controlling the inlet to said flush tank, a ball flush valve.

a concave valve seat for said valve, a discharge for the flush water and an outlet from said auxiliary tank to said discharge, the base of said auxiliary tank, valve seat, outlet and discharge being formed of a unit casting.

'2. In a valve construction for toilets and the like, the combination of a flush tank provided with an inlet and an outlet for the accumulated water, a valve in the inlet, an auxiliary tank for receiving the overflow from the flush tank, means in the auxiliary tank'for operating the valve and adapted to close the valve when the flush tank is filled to the proper depth and the overflow in the auxiliary tank reaches a predetermined level, an outlet from the auxiliary tank, and a single valve foropening and closing both said outlets for controlling the discharge from the flush tank and the auxiliary tank.

3. In a valve construction for toilets and the like having a flush tank, an inlet therefor and a discharge therefrom to the toilet, a valve in the inlet'for controlling the quantity of water passing to the tank, an auxiliary tank for receiving the overflow from the ilush tank, a float in the auxiliary tank connected to and operating the valve and adapted to close the valve when the overiiow in the iiush tank reaches a predetermined level, a discharge opening from each of the tanks and a single valve for normally closing both of the discharge openings and draining said flush and auxiliary tanks.

4. In a flush tank construction provided with an inlet and a discharge, 4an auxiliary tank therefor adapted to' receive Water when the flush tank is filled to the proper depth, means associated with said auxiliary tank and dependent upon the depth of water therein for closing said valve, a discharge from said auxiliary tank, and a valve member adapted to normally close and retain both said discharges in closed position except when the tank is being flushed.
